Hey,so I was trying to use the VND7020AJ as a driver to loads,and wanted to power the load to 7.2V while powering the high side driver with 12V.Im using a stm32f103rb,and using an outpin pin timer to control the pulse width to the input pin on the dr...

Hey I was I wondering if it was possible to use the x-nucleo-ihm08m1 on an 144 board.I only have 144 pin boards but couldnt find my board on MC Workbench.I also tried the motor pilot software and it said to configure the board.I suppose I can use it ...

Hey, probably a dumb question, but I couldn’t find it in the datasheet. Can each pin of the VNQ9025AJ handle 30A, or is that the rating for the smart switch as a whole with a limit on each pin? Honestly, I’m hesitant to believe a single pin can handl...

Hey,I'm planning to use this high-side driver in a project distribution module, but I'm having trouble fully understanding how the current sensing works.I've looked at the schematic, and I see a combination of two resistors, Rprot and Rsense. Is this...

Hey,I'm planning on building an ETC to control a throttle valve using the L9960 H-bridge. I'm currently in the process of designing a PCB for it. The driver is supposed to have 12V as VsV_sVs and handle up to 10A max as output load. The PCB I'm des...

Is there a specific pwm Frequency that I am supposed to follow or it can be just whatever?I am now testing a new board with VNQ9025AJ with the same problem.The schematic is the same and followed the datasheet recommend diagram.I was testing with a se...

Yes, I've connected the output pin and the board's ground/power ground to the load.I've tried adjusting the pulse width with the load connected and found that, to achieve the same output voltage, I had to change the IN1 signal for each load. For the ...

I've attached photos of the oscilloscope during testing. It seems that when the driver is connected to the load, it can't maintain a stable frequency. I've tested with 20 Hz, 100 Hz, and 20 kHz, but nothing really changed. Even though the frequency a...

Sure heres the full schematic.Page 1 is the connector,Page 2 is the power supply,Page 3 is the STM32,Page 4 is releated to the high side driver,Page 6 is related to the fuses of the outputs which are in series with the outputs.Page 5 and 7 are not re...

Oh,im sorry,I guess was dumb and didnt found it in the workbench.Now,how can I add the nucleo-f767zi in the workbench?Ive tried to import a board in the workbench but dont know where I can find this json. Also is there a problem to use the f756zG,I s...
